Description
I have started seeing this behavior after upgrading to 4.3.4. It is 100% repeatable on my system, and has a pretty significant impact on productivity.
The forum article I posted is https://forums.virtualbox.org/viewtopic.php?f=8&t=58909.
Reproduction steps: 1.) Start guest VM 2.) ssh into guest (localhost:2322 forwarded to guest:22 in my config) 3.) Perform any of the following operations:
a.) disable, then enable WiFi (issue occurs on enable, not disable) b.) disable VPN on host (happens with IPSecuritas and NetExtender VPNs on my system) c.) enable VPN on host
Expected behavior: no impact on ssh connection from host to guest
Actual behavior in 4.2.x: same as expected
Actual behavior in 4.3.4: ssh connection terminated, 'Connection to localhost closed by remote host.'
Config:
Host - MacOS 10.8.5, Guest - Ubuntu 13.04, 3.8.0-34-generic x86_64 Guest network - Paravirtualized network (NAT, natdnshostresolver enabled so that I can resolve VPN hostnames, but I have tested with it disabled and the same issue occurs) WiFi physical network connection
